Ingredients Explained

These ingredients are found in both products.

Ingredients higher up in an ingredient list are typically present in a larger amount.

Skin Conditioning

Retinol is a gold-standard ingredient for anti-aging. It is a form of Vitamin A and belongs to the class of retinoids that also includes tretinoin.

Why is retinol famous?

It has the most scientific studies backing up its skin benefits out of all the non-prescription ingredients.

Retinol is proven to:

This is why retinol is effective at removing wrinkles, fading dark spots, treating acne, and reducing the appearance of pores.

Studies show retinol is less effective when exposed to UV. Be sure to look for appropriate packaging to keep your retinol potent (similar to Vitamin C).

Using retinol or any retinoids will increase sun-sensitivity in the first few months. Though studies show retinoids increase your skin's natural SPF with continuous use, it is best to always wear sunscreen and sun-protection.

We recommend speaking with a medical professional about using this ingredient during pregnancy.

Retinol may cause irritation in some people, so be sure to patch test. Experts recommend 'ramping up' retinol use: start using this ingredient once a week and work up to using it daily.

BHT
Antioxidant, Masking

BHT is a synthetic antioxidant and preservative.

As an antioxidant, it helps your body fight off free-radicals. Free-radicals are molecules that may damage your skin cells.

As a preservative, it is used to stabilize products and prevent them from degrading. Specifically, BHT prevents degradation from oxidation.

The concerns related to BHT come from oral studies; this ingredient is currently allowed for use by both the FDA and EU.

However, it was recently restricted for use in the UK as of April 2024.

Antioxidant, Masking, Skin Conditioning

Tocopherol (also known as Vitamin E) is a common antioxidant used to help protect the skin from free-radicals and strengthen the skin barrier. It's also fat soluble - this means our skin is great at absorbing it.

Vitamin E also helps keep your natural skin lipids healthy. Your lipid skin barrier naturally consists of lipids, ceramides, and fatty acids. Vitamin E offers extra protection for your skin’s lipid barrier, keeping your skin healthy and nourished.

Another benefit is a bit of UV protection. Vitamin E helps reduce the damage caused by UVB rays. (It should not replace your sunscreen). Combining it with Vitamin C can decrease sunburned cells and hyperpigmentation after UV exposure.

You might have noticed Vitamin E + C often paired together. This is because it is great at stabilizing Vitamin C. Using the two together helps increase the effectiveness of both ingredients.

There are often claims that Vitamin E can reduce/prevent scarring, but these claims haven't been confirmed by scientific research.

Elaeis Guineensis Oil comes from the African Palm tree. This tree is native to Western and Southwestern Africa.

This oil is rich in antioxidants such as Vitamin E. Antioxidants may help with anti-aging.

The Vitamin E and fatty acid content give palm oil a skin-hydrating property. Emollients help trap moisture in by creating a film on the skin.

Palm oil is created by either squeezing the fruit or crushing the kernel at the center of the fruit. In the 1800s, archaeologists discovered a 6000 year old Egyptian tomb containing palm oil.

Palm oil is controversial due to its social and environmental impacts. Several organizations are working to make palm oil harvest more sustainable, such as the RSPO.

Broke me out
I have oily and acne prone skin and my face was on the road to recovery. I thought adding a retinol was a good idea and they marketed that this retinol oil is good for any skin type even though it is oily. It broke me out and gave me a scar within a week. It gave me an acne that was deep inside of my skin. I wouldnt recommend it to oily and acne prone skin people.

Every retinol that I have used caused my skin to be irritated and I wasn't able to continue using it, but this one is amazing. It's good for sensitive skin it's safe to use.
